As of November 26, 2024, this revision of Stealth Press 1 is considered a legacy version. We recommend downloading and building the Stealth Press 1S version instead.
Stealth Press 1 revision will remain accessible for reference purposes, as it is linked in numerous locations and has multiple community mods. This ensures continued access to Stealth Press 1 files for those who need them.
Stealth Press 1: Precision DIY Heat Set Insert Tool
Stealth Press is a highly accurate, mostly 3D-printed heat set insert tool compatible with generic, TS100/101, and Pinecil soldering irons. Key features:
Uses 300mm MGN12H linear rail for precision, simplifying construction;
Integrated, printable build plate for enhanced accuracy;
KEY-BAK key reel with kevlar belt loop for durability (1 million or more pulls);
Unique design improvements over similar DIY projects;
This user-friendly tool offers professional-grade performance without the need for costly extrusions.

Generic, TS100/101 or Pinecil.
Here are print guidelines for you to follow in order to have decent success with printing parts:
3d printing process | FDM (fused deposition modeling) |
Infill type | Grid, Gyroid, Honeycomb, Triangle or Cubic [1] |
Material | ASA, ASA-CF, ABS, ABS+, ABS-CF |
Infill percentage | 40% - 60% [2] |
Layer height | Recommended: 0.2mm |
Wall count | Recommended: 4 |
Solid top/bottom layers | Recommended: 5 |
Extrusion width | Forced 0.4mm |
[1] You can succeed with Support cubic infill type (slicer support may vary).
[2] As low as 25% infill for all parts if are aiming for faster print speeds and less filament usage. Consider using 60% of infill for build plate part to ensure it's not sagging over time.
PLA, PLA+, and PETG are also considerable filament choices. However, take into account that soldering iron radiates some indirect heat. The usage of less temperature-stable filaments may result in part deformations over time.
It is recommended to use PETG ir ideally - ASA or ABS at least for “arm” and “iron mount” parts.
A wall count of 4 is an absolute must to ensure the structural integrity of the parts. There is no need to go over the top with this. 4 are OK for this particular build.
The parts use this naming convention:
Primary color | These files will have nothing at the start of the filename. Example: buildplate_x1.stl |
Accent color | Files have “[a]” to the front of any STL file that is intended to be printed with accent color. Example: [a]_bushing_x1.stl |
Count of parts | Files have “x1” to “x4” at the end of any STL file. The number represents the count of identical parts to be printed. Example: [a]_m5_1mm_spacer_x4 (In this case you will need to print 4 identical spacers). |
Special thanks to Stefan and Alexander from CNCKitchen for backing this project by providing a generous set of soldering-iron tips and heat-set inserts for building and testing purposes.
Here is the list of other open-source projects used for sourcing multiple CAD parts. Models are used as-is or modified to fit the project purpose and design:
Date | Changes |
15.08.2024 | Complete update to information on this page, keeping it up to date. |
07.07.2024 | Version for Generic soldering iron mount added to support irons with 17mm (OD). |
27.03.2024 | Alternative version for build-plate WITHOUT sacrificial support is added as file: [extra]_no_sacrificial_support_buildplate_x1_r1.1. This version of build-plate should be printed with classic or tree supports. Serves as a back-fall/last resort to resolve reported issue with current sacrificial support sticking to the build-plate base too well, which can be result of over-extrusion or something else, unknown. Do not print both - regular and alternative version, you only need one. |
14.11.2023 | STLs for variations of generic soldering iron mounts were added supporting 18mm and 19mm (OD) irons. |
12.11.2023 | Minor update preparing for Dremel Add-On release. leg_x1_r1.1.stl is updated to leg_x1_r1.1_1.stl removing safety buffers. This was necessary to ensure cross-compatibility in between base parts and multiple add-ons in development. |
04.11.2023 | Printed files updated to R1.1. with cosmetic changes to ALL parts. (Note that mechanical parts - BOM is not affected, zero changes there.) Wire strain reliefs now have an extra opening for the M3 bolts solving an issue that the bolts were too hard to fit in. The LEG plate now has specific safety buffers preventing linear rail bearing carriage accidental slide-offs (Sometimes referred to as dropping balls :) Do not do that.) Ton of other incremental improvements optimizing general printability of parts even better than it was in Rev.1.0 |
10.10.2023 | .STEP files added for soldering iron mounts only (for all 3 currently supported types - Pinecil, TS100 / 101, and “Generic”. |
26.10.2023 | Minor changes in BOM - Key-bak Super48 36" 13oz variant as recommended. |
11.10.2023 | Initial version (Rev1) |
